Using the marks as a guide, turn compensating sprocket bolt ± degrees. m. Rotate compensating sprocket to make sure there is a light pressure on sprocket from the springs, no clearance should be felt. A slight rotation should be possible by hand with transmission in neutral. Clutch hub mainshaft nut has left handed threads, so turn counterclockwise to install. n. Clean and prime threads of nut. Apply two drops of LOCTITE THREADLOCKER (red) to the threads of the clutch hub mainshaft nut. Start nut onto mainshaft and tighten hand tight. 9. See Figure -8. Slide wedge () of primary chain tensioner in direction of arrow until all travel is removed. 0. Push shoe () down until it contacts wedge. Keep tension on shoe so wedge stays in place.. See Figure -9. Insert cable tie () as shown to hold wedge in place. Make sure end of cable tie is located below primary chain tensioner. If cable tie is installed this way, it will hang below primary cover gasket surface and serve as a reminder to remove cable tie before installing primary cover. Primary chain tensioner will not complete chain adjustment until vehicle is ridden. Vehicle must be test ridden after tensioner removal/installation to ensure proper adjustment.. See Figure -0. Install primary chain tensioner () into place. Install chain tensioner fasteners () and tighten to -9 ft-lbs (0.-.8 Nm). Remove cable tie.

S The lip garter spring side of the oil seal is also identified by the words "OIL SIDE". Install oil seal with a seal driver that will press only against outer rim of oil seal, NOT against the inner area. The minimum allowable depth of the seal is reached when the outer edge of the seal carrier is flush with the machined surface of the primary housing. The maximum allowable depth of the seal is reached when the seal carrier contacts the mainshaft bearing snap ring. 7. Install mainshaft oil seal: a. Lubricate the O.D. of the new seal with clean engine oil. b. See Figure -. With the lip garter spring side (stamped "oil side") facing toward the bearing, press squarely on the outer edge of a new oil seal until outer edge of seal is flush with machined surface of inner primary housing. 8. Lubricate the bearing and seal lip with multi-purpose grease or clean engine oil. sm08 MAINSHAFT BEARING INNER RACE PART NUMBER HD-90-B Removal TOOL NAME MAINSHAFT BEARING INNER RACE REMOVER/INSTALLER The bearing inner race must be positioned on the shaft a precise distance to properly align with the bearing outer race in the primary chaincase.

CLUTCH REMOVAL AND INSTALLATION To remove the clutch without disassembly or for installation instructions, see. DRIVE COMPONENTS, Removal. CLUTCH PACK ONLY Partial Disassembly This procedure can be performed on the motorcycle without removing the clutch shell or hub.. Remove primary chaincase cover. See. PRIMARY CHAINCASE COVER, Removal.. See Figure -. Remove six bolts () (metric) to release diaphragm spring retainer () from clutch hub. Loosen each bolt gradually and in a star sequence around the hub.. Remove diaphragm spring retainer, diaphragm spring () and pressure plate () from clutch hub.. Remove friction plates (, 7), steel plates (), damper spring (8) and damper spring seat (9) from clutch hub (). Continue with Cleaning And Inspection. Cleaning And Inspection Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates. (000a). Wash all parts in cleaning solvent, except for friction plates and bearing, if removed. Blow parts dry with low pressure compressed air.. Check friction plates as follows:. a. Blow off all lubricant from the friction plates. Do not wipe off with a rag. b. Measure the thickness of each plate with a dial caliper or micrometer. c. If the thickness of any plate is less than 0. in. (. mm), discard all friction plates and replace with an entirely new set. d. Look for worn or damaged fiber surface material (both sides). Replace all nine friction plates with an entirely new set if any individual plate shows evidence of wear or damage. Submerge and soak all friction plates in FORMULA+ TRANSMISSION AND PRIMARY CHAINCASE LUBRICANT (Part No. 998-0, qt.) for at least five minutes.. Check the steel plates as follows: a. Discard any plate that is grooved or bluish in color. Blue plates are likely warped or distorted. b. Check each plate for distortion. Lay the plate on a precision flat surface. Insert a feeler gauge between the plate and the flat surface in several places. Replace any steel plate that is warped more than 0.00 in. (0. mm).. Holding the clutch hub, rotate the clutch shell to check bearing for smoothness. Replace the bearing if it runs rough, binds or has any end play.. Check the primary chain sprocket and the starter ring gear on the clutch shell. Replace the clutch shell if either sprocket or ring gear are badly worn or damaged.. Check the slots that mate with the clutch plates on both the clutch shell and hub. Replace shell or hub if slots are worn or damaged. 7. Check the diaphragm spring and diaphragm spring retainer for cracks or bent tabs. Obtain a new diaphragm spring or diaphragm spring retainer if either condition exists. 008 Softail Service: Drive -
